of de facto states counted an overall population of more than 4 million people. The essays collected in this volume address such questions as: How do post-Soviet de facto states survive and continue to grow? Is there anything specific about the political ecology of Eastern Europe that provides secessionism with the possibility to launch state-making processes in spite of international sanctions and counteractions of their parental states? How do secessionist movements become embedded in wider networks of separatism in Eastern and Western Europe? What is the impact of secessionism and war on the parental states? The contributors are Jan Claas Behrends, Petra Colmorgen, Bruno Coppieters, Nataliia Kasianenko, Alice Lackner, Mikhail Minakov, and Gwendolyn Sasse.
